Copper plays an important role in a new model of hot water heater that claims to be one of the most energy efficient on the market.

The Bosch 32C uses condensing technology to create a 6-star energy rating and a level of energy efficiency at over 94%.  

Unlike traditional water heaters, Bosch’s condensing technology captures waste heat from exhaust gas and uses it to preheat incoming cold water.  The result is an energy-saving of more than 15.5%, compared to a standard continuous flow commercial water heating system.  

It is the only continuous flow system that can be installed internally or externally.   The unit has dual heat exchangers (primary  and secondary), enabling it to use residual heat from exhaust gases to help preheat incoming water prior to it entering a primary copper heat exchanger.

The copper heat exchanger is coated to prevent corrosion and deterioration, and the internal copper piping is 25% thicker than any other model.

The model has been designed for both commercial and domestic use where there is demand for large volumes of hot water. Its manufacturer claims that choosing this system for a commercial project is the equivalent of taking one and half cars off the road for an entire year, saving tonnes of greenhouse gas emissions and major dollars in terms of running costs.

Bosch 32C was developed in line with Australia’s Ecologically Sustainable Development (ESD) standards and in compliance with the Australian Building Code Board’s latest energy efficiency provisions.
